COMPRESSOR
Copeland Scroll Ultra Techt Two−Stage Compressor
I
Compressor features high
efficiency with uniform
suction flow, constant
discharge flow and high
volumetric efficiency and
quiet operation.
Compressor consists of
two involute spiral scrolls
matched together to
generate a series of
crescent shaped gas
pockets between them.
During compression, one
scroll remains stationary
while the other scroll orbits
around it.
Gas is drawn into the outer
pocket, the pocket is sealed as the scroll rotates.
As the spiral movement continues, gas pockets are
pushed to the center of the scrolls. Volume between the
pockets is simultaneously reduced.
When pocket reaches the center, gas is now at high
pressure and is forced out of a port located in the center
Slider Ring
Fixed scroll
efficiency.
Scroll compressor is tolerant to the effects of slugging
and contaminants. If this occurs, scrolls separate,
allowing liquid or contaminants to to be worked toward
the center and discharged.
On the fixed scroll there are two bypass ports in the first
suction pocket. On the outside of the fixed scroll there is a
slider ring" that is controlled by an internal solenoid that
will rotate and cover the bypass ports. When the
thermostat calls for first−stage cooling, the bypass ports
are open and the compressor operates at 67% capacity,
creating more cost−effective and efficient compressor
operation. The bypassed refrigerant is returned to the
compressor housing through the bypass ports. When
the thermostat calls for second−stage cooling, the
internal solenoid is energized, the slider ring rotates and
covers the bypass ports, and the compressor operates
at full capacity.
Low gas pulses during compression reduces
operational sound levels.
Compressor motor is internally protected from
excessive current and temperature.
Compressor is installed in the unit on specially
formulated, resilient rubber mounts for better sound
dampening and vibration free operation.
Internal solenoid
Slider
Ring

solenoid
of the fixed scrolls. During
compression, several
pockets are compressed
simultaneously resulting in
a smooth continuous
compression cycle.
Continuous flank contact,
maintained by centrifugal
force, minimizes gas
leakage and maximizes

FEATURES
COMPRESSOR (CONTINUED)
Crankcase Heater
Crankcase heater prevents migration of liquid refrigerant
into compressor and ensures proper compressor
lubrication.
Outdoor Thermostat Kit
An outdoor thermostat can be used to lock out some of the
electric heating elements on indoor units where two−stage
control is applicable.
Outdoor thermostat maintains the heating load on the low
power input as long as possible before allowing the full
power load to come on the line.
Thermostat kit and mounting box must be ordered extra.
Cabinet
J

multi−zone applications. Options include local interface,
software for local or remote communication, and
hardware for networking other control functions. See L
Connection Network Engineering Handbook Bulletin for
details.
Low Ambient Control Options
Air conditioners operate satisfactorily down to 45°F
outdoor air temperature without any additional controls.
Two low ambient control options are available for field
installation:
Low Ambient Control Kit (30°F)
Allows unit operation down to 30°F. See Optional
Accessories, page 7, for ordering information.
Low Ambient Control Kit (0°F)
Allows unit operation down to 0°F. This option requires
that the outdoor fan motor and capacitor be changed. See
Low Ambient Control Option table, page 7, for ordering
information.
A Freezestat should be installed on compressors
equipped with a low ambient kit.
A Compressor Low Ambient Cut−off should be added to
terminate compressor operation below recommended
operation conditions (on/off operation, 30°F or modulating
operation, 0°F).
Indoor Blower Off Delay Relay
Delays the indoor blower−off time during the cooling cycle.
See ARI Rating Tables for usage.
